I have a P2000 that has been my primary since 2010, until now as I'm shooting a SIG.
It has been dead nuts reliable in 25000 rounds. The only stoppages were from the slide impacting a barricade, 2 dud primers on cheap ammo, and 2 failures to extract on steel MFS. They don't seem to like steel cased ammo from my own experience and what I've read.
I think the P2000 has the best manual of arms in the market. Add in an HK45C mag release to mag make mag changes easy as can be. Note that I never really caught onto the LEM, mine is TDA.
I recently added some P30 mags with X-grips. I used to carry it with the 16 round German Police Model mags before I moved to NJ. I tried the flat 13 round baseplate and did not like them, greatly preferring the extended pinky rest. I really do love the gun, especially after it being my first serious use gun....but I find the trigger, recoil and grip of the classic SIGs to be more enjoyable...though I don't like the controls of the SIG. I've often thought that maybe the oft-forgotten USPc would be a better choice, as I can not only get the same Gray Guns trigger job I have now, but do it on a match trigger to start with. The USPc grip feels more secure, as well. Check it out.
